Steroids, Baseball and Climate Change

What do home runs and weather extremes have in common? A lighthearted animation explaining why some people call carbon dioxide (and the other greenhouse gases) the steroids of the climate system. Statistics and extreme behavior are involved, whether we're talking about baseball or Earth's atmosphere. National Center for Atmospheric Research (NCAR) scientist Gerald "Jerry" Meehl explains why. Length: 2 minutes Audience: All
